FIBECBACKER. AND PROCEEES OF IMAKIN'G THE SAME.

Application filed. January This invention relates to improvements in theformation of fire crackers and in the process of making the same.

of the objects of tie invention. is to provide a fire cracker entirelydevoid of end plugs and the like, the xplosi e matter being helr withina tubular container, with both ends thereof folded back upon itself andon opposite sides thereof, and a sin bent in the form of long loop withthe two ends of the fuse embedded within the explosive wihin thecontainer and the loop of the fuse extending out and beyond thecontainer and beyond the shell in which the container is placer; and thetubular con tai'ier after the ends have been folded back upon thecentral portion to bent l tudinally to form groove: the entire le of thefolded container, so that the ed the groove will be pressed towards eachsufficiently to permit the entire container 'to be readily inserted in asuitable shell, an then the edges of the groove to expand and impingeagainst the inner periphery of the shell and securely hold the containerin any determined position with the shell.

Further objects of this invention will ap pear from the disclosure inthe single sheet of drawings herewith made a part of this application,and in the following description.

In the several perspective views shown by the drawings:

Figure 1 represents the tubular container, with one end bent backagainst the middle section thereof, with the explosive being poured intothe other open end;

Fig.2, illustrates vertical sectional view of the container with acharge of explosive in the central section thereof, with one end of thecontainer bent back and flattened against the said central section, anda long fuse member in the form of loop, with the two ends thereofembedded within the explosive and the loop portion extending out fromthe tube.

Figure 3 represents the container with both ends bent back on oppositesides of the central section, and the three parts bent longitudinally toform a groov on one side thereof;

Figure 4- represents the container inserted within a larger and tubularfire cracker shell, in completed condition.

Like numerals on the different figures represent like parts.

1 is the outer shell, preferably formed in straight tubular form of thincardboard with the openings of same diameter at each end to permit theready insertion therein of the explosive container. 2 is a tubularcontainer for the explosive, of smaller diameter than the shell, andpreferably formed ofheavy paper with some resilient quality, into whichis inserted a fuse 3 in form of a loop, with the two ends thereof l and5 embedded within a charge of explosive 6, and 6 represents a supply ofexplosive being poured into the open end of the container. Beforesupplying the explosive, the lower end portion and approximately onethirt of the container is bent back at point 7 and flattened as 8against the middle section or pocket 9, thus closing the tube 2 at thebend to prevent the escape of the explosive, and the upturned end 8 alsoforms an additional sheath over the explosive and causes a loud reportwhen the explosion occurs. The other open end of the tube providesfacility for admitting the charge of explosive.

V lien a proper supply of explosive has been placed in the centralportion or pocket 9 of the container, the two ends of the fuse areinserted in the explosive at opposite sides within the container, thusinsuring greater certainty of igniting the charge when the loop end isfired, and the upper section -11 of the tube is tiien bent back atapproximately the line 10, and over the pocket 9 on the opposite sidefrom the end 8, for the purpose of closing the tube and preventing theloss of explosive, and to provide additional material to be burst whenthe explosion takes place. The two lines of fuse being atopposite sidesand against the wall of the tube will not be so tightly bound by thebent tube as they would be if centrally placed, as the folded edges tendto form spaces for the fuse, and this prevents the tendency of the firein the fuse being extinguished at the bend, as is frequently the casewhere the explosive containers are tied, etc. or twisted as in ordinarymethods of fastening explosive containers for fire crackers.

The two edges 12 and 13 of the section 11 and the corresponding edges ofthe sections 8 and 9 are then bent longitudinally one behind the otherthus forming a groove 14 the length of the sections, and as these edgesare compressed towards each other and the groove narrowed, the outsidecircumference of the folded container will be sufficiently reduced to bereadily inserted into either end of the tubular holding shell 1 to theposition desired therein. The resiliency of the compressed portions ofthe container when placed in the shell causes the edges 12 and 13 andthe curved end 8 to expand and impinge sufiiciently against the innerperiphery of the shell 1, to securely hold the container in any desiredposition within the shell to which it has been placed, without the useof cement or other usual means.

Having described my invention, what I claim as new is;

1. A tubular container for explosive for fire crackers, with each end ofthe tube bent back and flattened against the central portion thereof,with a fuse extending from a charge of explosive in the container outbeyond the container end, and both end portions and the central portionof the container bent longitudially along one side to form a concavesurface on that side with the bent edges of the portions expanded to anouter shell for holding the container within the shell.

2. A fire cracker with an outer tubular shell, and a charge of explosivematter within a tubular container, with a fuse bent in form of loop withthe loop portion extending beyond the shell and the two ends of the fuseembedded within the explosive and the two sides of the fuse loop lyingwithin the container at opposite sides thereof, with both ends of thecontainer bent back against the central portion thereof and on oppositesides thereof for holding the explosive in the central portion and tocause a loud report, and the edges of the bent portions pressed towardeach other to form a groove longitudinally between the same, and theedges to bind against the inner periphery of the shell for holding thecontainer in place.

3. The process of forming a fire cracker by placing a charge ofexplosive in a flexible tubular container, with a fuse extending fromthe charge out from one end of the container, and folding both ends ofthe container back over the central portion contain ing the charge, andbending the edges of the central and folded portions of the containertoward eachv other on one side to form a groove longitudinally with theedges forming resilient expansive means for bold ing the container witha tubular shell, which is placed over the explosive container.

In testimony whereof I afiix my signature.
